We really like the new Potenza Sport, as it’s more sporty and dynamic than the usual tyre in this category, but still perfectly usable and safe for everyday driving, which makes it unique. It’s rolling resistance, mileage and overall comfort are also on a good level, except for a slighty higher noise.

Bridgestone Potenza Sport ( 245/40 ZR20 (99Y) XL EVc )
The Turanza 6 is quite a new addition to Bridgestone’s lineup, being introduced in 2023. Featuring the new ENLITEN technology, it should be lighter and have positive effect on fuel efficiency. In the tests, the efficiency is confirmed alongside with higher mileage. That being said, it somehow lacks the performance of other premium tyres, so we would recommend it only when the price is lower.
The P Zero range is with us for a long time, also being a favorite choice for car manufacturers as first equipment. It’s a good, well balanced and enjoyable tyre. It tends to get quite a few mid-life updates so make sure you get the latest one.
245/40 R20 doesn't belong to the most popular dimensions for summer tyres - there are 37 tyre models available, which can be compared to 235/40 R18, 195/50 R16, 160/60 R17. Let's break down the sizing - 40 is height of the tyre, which is calculated as 40% of the tyre width (245mm), which means the sidewall height has 98 mm. The wheel diameter is R20, which means it fits to a 20 inch/508mm diameter wheel. The total circumference of the tyre is 2211.68 mm, which is very similar to 285/30 R21(2212.94 mm), 215/75 R15(2210.11 mm), 275/45 R18(2213.88 mm), 225/55 R18(2213.88 mm), 245/35 R21(2214.51 mm), 245/45 R19(2208.85 mm), 275/40 R19(2207.28 mm).
